Would you rather do business with companies that treat you well or treat you like dirt? It’s a no-brainer. And, each quarter, the University of Michigan gives you that information on a silver platter. This quarter, UM rated the top customer service oriented companies in the airline, fast food and phone industries. In the cell phone industry, T-Mobile and Verizon were listed as the best. Cingular, Nextel and Sprint tied for dead last. In the traditional phone business, AT&T, Verizon, BellSouth and Quest all got lousy scores. The top company was Cox Communications, which provides cable and phone out West. In the pay TV industry, DirecTV got top honors, followed by Dish. The cable companies – Comcast and Charter – were ranked toward the end. What about the airline industry? The best airline without question was Southwest, and the other discounters fared pretty well. The worst by far was Northwest. The only full fare airline that got a half decent rating was Continental. As far as fast food, Papa John’s got the highest score for the second year in a row, and McDonald’s brought up the rear. Overall, the cable industry got the lowest score of any of them.
